At present, the more common signal transmission specifications are USB2.0, USB3.0 (USB is the abbreviation of Universal Serial Bus) and ESATA (short for External Serial Advanced Technology Attachment), so it has developed A composite socket electrical connector for plugging USB2.0, USB3.0 and ESATA plug connectors, for example, Taiwan New Patent Publication No. M357748 (corresponding Chinese Patent Application No. 200810173163.4; corresponding US Patent Publication No. US20091 11 330A1) Revealed. A preferred embodiment disclosed in the patent No. M357748 is an assembled structure using a split tongue and includes three types of terminals, wherein the first type of terminal is an ES ΑΤΑ connector terminal and the second type of terminal is a standard USB 2. The 0 connector terminal, the third type terminal and the second type terminal cooperate to form a USB3.0 connector terminal, and the third type terminal and the tongue plate are integrally formed and embedded in the tongue plate, and the first contact portion of the first type terminal is mounted on the The 3 M406863 upper surface of the tongue plate's second contact portion of the second type terminal and the third contact portion of the third type terminal are mounted on the lower surface of the tongue plate. However, the general ESATA terminal (first type terminal) and USB3.0 The terminals (terminals of the third type) are all used to transmit high frequency signals, while the patent No. M357,748 discloses that in the butting direction, the third contact portion is located in front of all of the first contact portions and all of the second contact portions. That is, the contact portion of the USB3.0 terminal is located in front of the contact portion of all ESATA terminals and the contacts of all USB2.0 terminals, but the USB3 〇 terminal includes terminal pairs for transmitting the frequency condition number (for example, differential pair, differential Pair), if there is no better masking, it will reduce the speed of signal transmission and increase the distortion of the signal. [New content] Therefore, the object of the present invention is to provide a socket connector which can reduce the crosstalk phenomenon of a high frequency signal pair and stabilize the transmission impedance of a signal. According to a preferred embodiment of the present invention, the socket connector includes an insulating base, a metal housing outside the ash holder, and a second terminal set. The tongue is green.
